PATENT OFFICE.

BOILER.

SPECIFICATION forming part of Letters Patent No. 405,757, dated June 25,1889.

Application filed February 1, 1889. Serial No. 298,315. (No model.)

To all whom, it may concern.-

Be it known that I, JAMES BAUER, a citizen of the United States ofAmerica, residing at York, in the county of York and State of Nebraska,have invented certain new and usef ul Improvements in Boilers, of whichthe following is a specification, reference being had therein to theaccompanying drawings.

This invention is directed to an improvement in water-heaters especiallydesigned to heat or Warm a surrounding body or column of water; and itconsists of a receptacle or tank having an annular water space orchamber and cent-rally thereof a combustionchamber, being adapted tocontain a fire-grate applied to an ash-pit having a draft-opening inalignment with an air-inlet pipe suitably valved, While to a removablecover supplied to the inner chamber of the receptacle or tank isfurnished a valved smoke exit or stack, as will be more fully understoodfrom the following description and illustration, in which- Figure 1 is asectional elevation of my improved heater; and Fig. 2 is a similar viewof the combined fire-grate and ash-pan removed from the tank orreceptacle, and with its manipulating or removing hook applied theretoas in use.

In the embodiment of my invention I employ a tank or receptacle A,having an annular chamber or compartment to to contain or hold water,inlet and outlet pipes a a, being provided for supplying the waterthereto for heating and for its withdrawal after having been heated.This tank or receptacle has also a central or inner chamber orcompartment a being the combustion chamber, within which is placed ordisposed the ashpan B, having combined therewith a firegrate B, securedupon the upper edge of the pan. The ash-pan has a draft-opening b in oneend.

C is the air-inlet pipe, having an air-regulating valve or damper c inits outer portion. This pipe is arranged in alignment with and has itsinner end opposite to the draft-open ing 12 of the ash-pan to supplytherethrough, under the fire-grate, the requisite amount of air to aidcombustion.

The central or combustion chamber a is fitted at its top edge with acover D, which has a central smoke-exit pipe or stack d, also providedwith a valve or damper d for controlling the draft.

E is a handled or looped hook, which is adapted when grasped by the handto engage or take hold of the fire-grate and permit of the convenientand expeditious lifting of the ash-pan with the fire-grate out of thecom bustion-chamber of the tank or receptacle when the same needs theremoval of the ashes, &c.

By the aforesaid arrangement of parts it will be observed that thedirect or immediate action of the caloric or heat is exerted or causedto impinge upon the water in the tank or receptacle, thus expediting theheating or warming of the water, while it is readily withdrawn whenrequired for use as above noted.

Having thus fully described myinvention, What I claim, and desire tosecure by Letters Patent, is

The water-heater having the outer annular water-chamber, the central orinner combustion-chamber, the combined ash-pan and firegrate, the coverhaving a valved central smoke exit or stack, and a valved air-inlet pipearranged in alignment with and having its inner end opposite adraft-openil'lg in the ashpan, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES BAUER.
